tircd is an ircd proxy for talking to the Twitter API. It should work with any standard IRC client. After running the Perl script, you authenticate to the IRC server using your Twitter username as your /nick. Join the room #twitter and the /topic will be set to your last update. Any message you type will update Twitter and the room’s topic. All of the people you are following show up in the room as users and post messages as they tweet. If you private message one of them, it will become a direct message on Twitter. Other commands work too: /whois to get a person’s bio, /invite to start following, and /kick to unfollow. The project is brand new and will be added new features in the future like Search API support. Follow @tircd for updates.

The GP2Y0D02 is an infrared proximity sensor with a detection field that extends 80cm. This type of sensor can be used to build collision avoidance systems for robots. We’ll demonstrate this sensor using a single resistor and a multimeter.

[matiaz] has released an exploit which allows homebrew on the PSP3000. It takes advantage of a vulnerability when loading save games on a game called GripShift. You can see the PSP running unsigned code in the video.

[rog8811] sent in this really cool hack where he used the optics sled from a PS3 as a foundation for a 7 color hand held laser projector. Combining a green laser, a blue ray laser, and a red laser, he is able to produce a variety of color including white. There are step by step instructions on how to make a multicolored laser. He then goes even further, showing how to integrate this into a hand held projector with pre programmed patterns. You can see some examples of the different colors and patterns in this video.
